This kind of watches is made_______plastic.And they are made in Guanggzhou.
是of还是from

填 from
This kind of watches is made from plastic.And they are made in Guangzhou.
这种手表是由塑料制成.它们是在广州制造的.
【解析】
be made of和be made from 都表示"由…制成",主语为制成品.
be made of 表示制成成品后,仍可看出原材料.
be made from 表示制成成品后,看不出原材料.
再问：成品表应该是看得出来是塑料做的啊，所以为什么不用of？？
再答：其实很难辨别的，有的手表是钢化玻璃，合金，薄钢等材料，看过去不一定一下子看的出来。此外，塑料这种原材料本身也是多样化的，一般我们说有塑料制成都是用 be made from
